C :

#include <stdio.h>

int main()
{
    int a,b;
    scanf("%d %d",&a, &b);
    printf("%d\n",a+b);
    return 0;
}

C++ :

#include <iostream>
using namespace std;
int  main()
{
    int a,b;
    cin >> a >> b;
    cout << a+b << endl;
    return 0;
}

Java :

import java.io.*;
import java.util.*;
public class Main
{
            public static void main(String args[]) throws Exception
            {
                    Scanner cin=new Scanner(System.in);
                    int a=cin.nextInt(),b=cin.nextInt();
                    System.out.println(a+b);
            }
}

Python :

a = input()
a = a.split()
b = []
for i in a:
        b.append(int(i))
print (sum(b))

#include<bits/stdc++.h> using namespace std; int main() { int a,b; cin>>a>>b; cout<<a+b; return 0; }

#include<iostream>
using namespace std;
int main()
{
	int a,b;
	cin>>a>>b;
	cout<<a+b;
}

#include<bits/stdc++.h> using namespace std; int a,b; int main() { cin >> a >> b; cout << a+b; return 0; }

#include<bits/stdc++.h> using namespace std; int a,b; int main() { cin >> a >> b; cout << a+b; return 0; }

int a,b; cin>>a>>b; cout<<a+b;

```
#include<iostream>
using namespace std; 
int main()
{
    int x,n;
    cin >>x>>n;
    cout <<x+n<<endl;
    return 0;
}
